This study systematically revised the literature to answer the following question: do modeler liquids (MLs) affect the properties of direct resin-based composites (RBCs)?
The review followed the PRISMA statement, and the search was conducted in PubMed, Scopus, Web of Science, Embase, and Lilacs databases. Studies were included if they investigated the properties of RBCs prepared using the restorative dental modeling insertion technique (RDMIT). The risk of bias was performed with the RoBDEMAT tool. Statistical analyses were conducted using Review Manager, and heterogeneity was assessed with the Cochran Q test and I statistics.
From 309 studies identified, 25 met the eligibility criteria, and 23 were meta-analyzed. In total, 27 MLs and 23 RBCs were evaluated. Modeled and non-modeled RBCs showed similar results in terms of cohesive strength, flexural strength, load-to-fracture, modulus of elasticity, work of fracture, degree of conversion, solubility, weight change, microhardness, and color change. Sorption and roughness benefited from the use of MLs, whereas translucency and whitening index were more adequate in the non-modeled RBCs. Aging affected similarly the modeled and non-modeled RBCs. Most studies showed a moderate risk of bias.
Modeled and non-modeled RBCs performed similarly in most of the properties, and the use of non-solvated lubricants offered beneficial effects in some cases.
When a balance has to be made between the RDMIT and the conventional technique, our review supports the safe application of modeler liquids for the handling of composite increments during the sculpting fabrication of direct resin-based restorations.
本研究系统地回顾文献以回答以下问题：造型液体（MLs）是否会影响直接树脂基复合材料（RBCs）的性能？
本综述遵循PRISMA声明，在PubMed、Scopus、Web of Science、Embase和Lilacs数据库中进行检索。如果研究调查了使用牙科修复造型插入技术（RDMIT）制备的RBCs的性能，则纳入研究。使用RoBDEMAT工具进行偏倚风险评估。使用Review Manager进行统计分析，并通过Cochran Q检验和I统计量评估异质性。
从识别出的309项研究中，25项符合纳入标准，23项进行了荟萃分析。总共评估了27种MLs和23种RBCs。在内聚强度、弯曲强度、断裂载荷、弹性模量、断裂功、转化率、溶解度、重量变化、显微硬度和颜色变化方面，造型和未造型的RBCs显示出相似的结果。吸附和粗糙度受益于MLs的使用，而透明度和美白指数在未造型的RBCs中更合适。老化对造型和未造型的RBCs的影响相似。大多数研究显示存在中度偏倚风险。
造型和未造型的RBCs在大多数性能方面表现相似，在某些情况下使用非溶剂化润滑剂具有有益效果。
当必须在RDMIT和传统技术之间取得平衡时，我们的综述支持在直接树脂基修复体的塑形制作过程中安全应用造型液体来处理复合增量。
